Parks and Trails

Bike Skills Park and Challenge Trail

Updated October 2020

The City is partnering with the Evergreen Mountain Bike Alliance to bring this long-awaited amenity to Central Park. Evergreen is renowned for their design expertise and for supporting the mountain bike community. They are the main partner at Duthie Hill Mountain Bike Park.

In 2018, three concepts for the Central Park skills park were presented to the community in an online survey and at a public meeting at Blakely Hall. Both efforts generated valuable input and feedback that was used to create a preliminary design for the bike park, a “hybrid” of the three concepts.

Construction was planned for 2020. Due to county budget shortfalls, City of Issaquah did not receive grant funding expected in 2020. Therefore the bike skills park will not be built until 2022 at the earliest.

If you are interested in being on the bike park communications list, please email Jennifer Fink at .

Neighborhood Parks and Trail

Late in 2018 the new trail around Westridge South opened to the public. Access is at the SW corner of Swedish Hospital property, or at the driving entrance to Westridge South. In places a forest path and in others paved like a sidewalk, stairs and curves create a delightful, shaded pathway.

The Alexan apartments (Block 19) will include a public path connecting Sunset Pond with 10th Ave NE and the pocket park north of Marshall’s.

By 2020 expect to see the Westridge neighborhood parks completed, one with a small splash park and another with more community garden patches.

Throughout Westridge new pedestrian trails will be created, especially for east-west travel. Traversing these you will be able to connect to the now open Westridge South forest edge trail and the future High Street Linear Park.

High Street Linear Park

High Street Linear Park was approved by the City Council in July 2018. The park will be built by Polygon Homes NW and will convert a portion of High Street into a multi-use trail for non-motorized travel. Amenities and recreation will be placed along its quarter-mile length. The park will be approximately 31,000 square feet total.

In November and December 2018, the City and Polygon surveyed the community about potential amenities for the park. Stand-out requests include:

  • Seating and gathering areas that take advantage of the views
  • Sheltered seating and gathering areas
  • Play areas for all ages, especially older kids and teens
  • Flexible open spaces of grass or park plazas
  • Table tennis, court games
  • Hillside climbing
  • Telescopes
  • Water feature for all ages

Although an off-leash dog area was desired, careful consideration must be taken to determine true suitability of this location.

Almost 90% of respondents were IH residents

Project Timeline:

November 2020: Work begins on High Street Park. The IHCA is now working with Taylor Morrison, the new developer of Westridge (acquired Polygon Homes in 2019).

January 2020: High Street is now closed. NE Ellis Drive and NE Discovery Drive are now the access roads for West Highlands Park.

Q1 2020: High Street closes as soon as the western extension of Ellis Drive opens providing access to West Highlands Park. Site development in preparation for the park begins.

The Urban Village Development Commission (UVDC) is scheduled to review preliminary designs on March 26, 2019. Watch for details here>>>.

Central Park

Central Park Pad 2 baseball fields are in Issaquah Parks Strategic Plan to have artificial turf installed (and lighting?).

Central Park Pad #1 was rebuilt in 2017-18 with updated sports fields with artificial turf, drainage, fencing and LED field lights, path lights and scoreboard, etc.

Improvements also featured unique public art by artist, Lydia Aldredge, commissioned by the City of Issaquah’s Arts Commission.

City of Issaquah held a ribbon cutting for Pad 1 on Saturday, March 17, 2018.

The City of Issaquah Parks Strategic Plan was adopted in July 2018. In it are plans for Pad 2 baseball fields (near term) and Pad 4 open space (mid-long term).

School Siting | Follow up:

As of January 2019

In 2018 Issaquah School District (ISD) considered a property on the western border of Issaquah Highlands, west of Swedish Hospital, for a new elementary school. After thorough site analysis (including geotech and arborist studies), ISD decided not to pursue the property for a school.

In June, ISD announced they would be building a new elementary school on what’s referred to as the Volpe property on Issaquah Pine Lake Road, approximately 2 miles from Issaquah Highlands.

To wrap the year up, ISD purchased land in Talus for its sixth middle school and will retain the property in downtown Issaquah (current Administration Center) for future use.

The Issaquah School District posted an update on Saturday, May 5, 2018.

This update covers the topics explained in the blog post reporting on the School Board meeting of April 25, 2018.

Shelter Holdings | IHIF-C:

As of February 2020

Shelter Holdings (through their affiliate IHIF Commercial, LLC) continues to pursue their plans to develop the 21.5 acres, undeveloped L-shaped property (formerly owned by Microsoft) located west along 9th Ave. NE and Discovery Drive. They are allowed to develop up to 1.8 million square feet of commercial/retail space, plus three residential units.

However, Shelter Holdings applications for three site development permits are in dispute with the City. These applications were submitted to the Development Commission in September 2018 for review and public comment. This review has continued over several months. On July 2, 2019 the Development Commission denied all three applications.

January 2020 update: These application denials have been in appeals ever since.

Shelter Holdings Applications, Lot by Lot:

  • 111,000 square feet of retail development
  • 143,000 square foot office building with ground floor retail
  • 92,000 square foot medical office building, with ground floor retail or commercial uses

Helpful Development Terms

Affordable Housing (distinct from low income housing):

As governed by the Issaquah Highlands Development Agreement (DA), 30% of residential development shall be “affordable housing”. The DA further defines “affordable” as that which is calculated as affordable to those earning 80, 100 and 120% of the King County median income. (Currently, the King County household median income is $73,000.)

Audience Comments:

An opportunity to speak publicly, addressing a body such as the City Council, on a topic that is not scheduled for a Public Hearing at that meeting. City Council provides this opportunity at the beginning of each meeting. The UVDC and City Council committees also welcome audience comments. (See specific agendas on the City website.)

Commercial Uses Include:

Office, Hotel, Restaurants, Fitness, Entertainment, Warehousing/Storage, Light Manufacturing, etc.

Development Agreement (DA):

An agreement (contract) between a land owner and a jurisdiction, such as a city, that determines how a property will be developed. The agreement has a term (i.e. 20 years) and “runs” with the land, if sold. The Issaquah Highlands Development Agreement was signed in 1996.

End of DAs:

A casual reference to the end of buildout period of the Issaquah Highlands Development Agreement (DA), and the agreement’s termination. Even though undeveloped properties remain in the Highlands, the City or the Master Developer can choose to terminate the DA at the end of the buildout period, which occurs in 2017.

Amount of residential, commercial or institutional development allowed by a contract such as a Development Agreement.

Institutional Uses Include:

Schools, Churches, Cultural Facilities, etc.


In September 2016, the City of Issaquah enacted a six-month moratorium on certain types of development. There are many exceptions. Notable to Issaquah Highlands is that all land governed by Development Agreements is excluded. In February 2017 the City Council extended this moratorium to September 6, 2017.

Public Hearing:

A scheduled opportunity to speak on the record on a specific topic. The Urban Village Development Commission (UVDC) and City Council both hold Public Hearings. Public notice of a hearing will be provided at least 10 days in advance. Sign up on the City’s website, “Notify Me” to receive email notices of Public Hearings.

Retail Uses Include:

Stores and Shops, Grocery Stores, Banks, Winery/Brewery, etc.

Site Development Permit (SDP):

When a development is large or complicated the Site Development Permit application process is used, which includes a Public Hearing.

Transfer of Development Rights (TDR):

Transfer of Development Rights (TDR) is a voluntary, incentive- based program that allows landowners to sell development rights from their land to a developer or other interested party who then can use these rights to increase the density of development at another designated location.

Urban Village Development Commission (UVDC):

A commission serving by appointment of the Mayor to review and approve (or recommend to approve) applications to develop land in the city’s Urban Villages, such as Issaquah Highlands.
